Atomic OSSEC vs Wazuh

Atomic OSSEC is an endpoint detection and response system that also protects cloud workloads and APIs. Its monitoring covers intrusion detection, file integrity, log management, active response, and vulnerability management. A GUI centralizes management of agents, servers, events, file integrity monitoring, rollbacks, and third-party integrations. The product lists more than 5,000 preconfigured OSSEC rules and out-of-the-box integrations for Splunk, ArcSight, ELK, and QRadar. It supports AWS, Azure, and GCP, and offers compliance reporting for frameworks including PCI DSS, HIPAA, NIST, GDPR, and CIS. Deployment can be on premises or cloud-based SaaS, including in air-gapped environments. The maker also describes support for legacy systems such as Windows, Linux, AIX, HP-UX, and Solaris, plus monitoring of operational technology without agents on sensitive equipment. A 14-day trial covers up to 10 licenses and does not require a credit card. The listed plan price is priced on request, pricing starts at $55 per agent, and bulk discounts are available; a separate pricing note says from $5/mo.

Wazuh unifies XDR and SIEM to analyze security data across endpoints, clouds, and networks for threat detection, incident response, and compliance work. Its rules identify errors, misconfigurations, malicious activity, and policy violations in operating system and application logs. File Integrity Monitoring tracks changes to content, permissions, ownership, and other file attributes. Vulnerability detection compares endpoint software inventories with updated CVE databases. Built-in active responses can take countermeasures, including blocking network access from a threat source. Wazuh can monitor AWS, Microsoft Azure, Google Cloud, Microsoft 365, and GitHub services, virtual machines, and activity. Its integrations guide also covers Elastic Stack, OpenSearch, Splunk, and Amazon Security Lake. Default rulesets provide mappings for PCI DSS, HIPAA, NIST 800-53, TSC, and GDPR, but those mappings do not themselves certify compliance. Wazuh runs on API, Linux, macOS, self-hosted, web, and Windows platforms. Its self-hosted open-source plan is free; paid plans start at $571 a month, and a 14-day trial is listed. Agents support Linux, Windows, macOS, Solaris, AIX, and HP-UX and require an average of 35 MB of RAM.
